Dr. Sheldon Cooper is smarter than you - and he's not afraid to say so! A theoretical physicist possessing a master's degree, two Ph.D.s, and an IQ of 187, Sheldon is originally from East Texas, where he was a child prodigy, starting college at the age of 11. He has zero interest in romance, as his only real love is science (although his "girlfriend" Amy is constantly finding loopholes in their "Relationship Agreement" to disprove this theorem). He's a stickler for routine and is very different from his family; his mother Mary is a devout Christian, and his twin sister Missy is not a scientist by any means. Superpowers: eidetic memory, vexillology, Tuvan throat singing. Weaknesses: understanding sarcasm, driving.
In The Big Bang Theory, Leonard and Sheldon are brilliant physicists - geniuses in the laboratory, but socially challenged in the real world. Enter beautiful street-smart neighbor Penny, who aims to teach them a thing or two about life. Despite their on-again, off-again relationship in the past, Leonard believes he's found true love with Penny. Even Sheldon has found a female companion, entering into a "Relationship Agreement" with neurobiologist Amy Farrah Fowler. In their free time, Leonard and Sheldon continue to enjoy frequent trips to the comic book store and fantasy role-playing games with their ever-expanding universe of friends, including fellow scientists Raj and Howard, and Howard's adorable microbiologist wife, Bernadette.
